Product Description:

The HDS03.2-W100N-HA13-01-FW is a power electronics module manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. It occupies a single slot in a modular servo rack and manages one motor axis by converting DC bus power into controlled three-phase output. In packaging lines, machine tools, and material-handling systems, the unit provides the regulation layer between the central motion processor and the motor so positioning, speed, and torque commands can be carried out accurately under changing loads. Because it works from the shared DC bus of the rack, it fits systems where multiple servo axes are coordinated from one control platform.

The command communication interface is analog, so the module accepts ±10 V reference signals without digital fieldbus communication. This interface style suits applications that use conventional voltage-based command signals from higher-level control hardware. A power channel rated at 100 A feeds the inverter stage, giving the axis enough current for rapid acceleration and controlled regenerative operation. Cooling is provided by a built-in air blower, which moves cabinet air across the heat sink to keep the power semiconductors within their operating temperature range. The unit is part of Line 03.

Within the DIAX04 family, the controller is built as Version 2. Its connector layout, mechanical size, and module spacing match the arrangement used in compatible multi-axis racks. That arrangement allows neighboring modules to share rack infrastructure without special offsets or extra clearance between slots. It also supports consistent bus bar alignment and directed airflow when several axes are installed side by side. The rack-based format helps keep power distribution and cooling paths orderly in cabinets where several servo axes operate together.
